ELECTRlC HAlR-BRUSH.

SPECIFICATION forming part of Letters Patent No. 462,599, dated November 3, 1891.

Application filed August 3, 1891.

T0 alt whom it may concern-.-

Be it known that I, ALEXANDER STANTON, a citizen of the United States of America, residing at Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Electric Brushes, of which the following is a specification.

My invention relates to that class of hairbrushes known as electrical hair-brushes, in which a current of electricity is caused to act upon the scalp through the tufts or knots when the brush is in use.

My invention is an improvement in the de tails of construction of the electric apparatus and the'casing in which it is located and the connection with the tufts or knots. It is illustrated in the accompanying drawings,'in which- Figure 1 shows a central longitudinal and vertical section of the brush. Fig. 2 shows a plan view of the back of the brush with the" casing removed.

In the drawings, A represents the brushstock, which is of the ordinary form of the material, such as wood or equivalent substance. In thisare thek1'1ots,tut'ts,orbunches n, which are secured as shown in the fig ures. These are made of any suitable kind of fiber, which must be in whole or in part conductorsof electricity. I prefer to use a vegetable fiber made of what is known as the Columbia grass. lVith this I mix fine metallic Wires, preferably of copper, (shown at cc,) which form electrical connection between the scalp and conductors, hereinafter explained, when the brush is in use. Upon the back of the stock is secured a casing, preferably of cast-iron. This is divided by a horizontal partition 2). The uppercompartment C is adapted to receive the battery, which is shown therein in position. It consists of two plates, one of copper and the other of zinc, each surrounded by the asbcstus packing, which is moistened by sulphuric acid. The

casing is provided with a plug E, fitted in an opening through which the acid is introduced. The wires ct f lead from these plates, respectively, to the primary wire of an inductioncoil (Z, located within the lower chamber. The connection through the wire a from one plate is through the binding-posts b c with Serial No. 401,488. (No model.)

one end of the inductioircoil, these posts being properly insulated. The other wirefis carried to the other terminal of the induction eoil through a hole in the partition 2). The wire a may be disconnected by loosening the screws of the binding-post whenever it may be desired to interrupt the current. The wires a and f are insulated. The secondary wire of the lllCltlCtlO11-COll has its ends 9 and 7L connected to the'ends of the spirallyarranged wire m. This wire is of copper, and it extends over the inner rows of the tufts and is in contact with the small copper wires :0, which bind the tufts in the wooden plate or-stock ot' the brush. The wire or is divided, one part terminating at and the other at .2", the parts alternating with each other. The current, therefore,is interrupted through the wire m; but the tufts arein electrical connection with the parts of the said wire in, one row with one part and the other row with the other part. The conductivity of the tufts is increased by the fine copper wire mixed therewith, and the circuit of the wire m is completed through the scalp be tween the tufts when the brush is in use.

I claim as my invention 1. In combination, the brush-stock, the easing having compartments formed by the horizontal partition, the battery in one compartment and the tufts having the connections extending through the other compartment,

said casing being connected to the stock, as

set forth.

2. In combination, the brush-stock, the easing having a compartment for the battery, said battery consisting of the plates and the moistened packing, and the wires a and f, connected to the tufts, as described.

3. In combination, the brush-stock, the easing containing the battery in the upper compartmentconnected with an induction-coil in the lower compartment, and connections to the tufts, and a detachable outside connection to break the circuit, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ALEXANDER STAN ON.
